The most common access to the scanned articles is from the ADS
Abstract Service results page via the "G" or "F" links.
The "G" link displays a document containing images of the
scanned article pages, while the "F" link returns a
Postscript or PDF file containing the entire article.
Links to images of the scanned pages or to the full-text article
in Postscript or PDF format
are also available from the page displaying the full bibliographic
information for a record in the ADS abstract system.

The scanned pages and articles can also be accessed
directly through the Article Service by volume and page at:

The forms listed in this page
allow users to specify a volume and page to be displayed
in the browser. If a volume but no page number is entered, the entire
table of contents for the volume in question is returned instead.

The default viewing mode for scanned pages displays a screen divided
in three panes, with the requested page occupying the main one.
On top of the scanned page, a separate pane displays the basic
bibliographic information for the article, with a link named "Other
article options" that takes the user to a simpler page-by-page view of the
article (called "classic" view mode) which contains additional
viewing options, including the capability to extract data from
the image using Dexter.
Also available in the top
pane are links to retrieve a fulltext document for the article
and to see its full bibliographic record in the ADS.
If the page to be displayed is part of an article (as most are),
thumbails of the other pages within the article are displayed
in the left navigation bar. Clicking on a thumbnail will display the
corresponding image at full resolution.

In the "classic" view mode, additional pages within the article or
section can be viewed by using the navigation links, forward/back,
located on the top of the Article Page or the links to any individual page
of the article listed below the scan. As an alternative to this
single-page browsing mode, users may choose to view the set of
low-resolution images for all pages composing the article by selecting
the "Thumbnails" link at the top of the Article Page. When viewing
thumbnails, a high-resolution image of each page can be displayed by
clicking on the corresponding thumbnail.

Other options available from this screen include the ability to
retrieve the full bibliographic record and abstract for the article
being viewed and in some cases the ability to retrieve a particular
plate number. If the article being viewed appeared in a publication
that printed the plates at the end of a volume and the plates have not
been assigned to the article they belong to, then an option to display
a given plate number will be available. The plate number discussed
here refers to the sequential number assigned to a plate within a
journal volume, and is typically referred to in the full text of the
paper. Users must read the article to decide if there is a plate
associated with a given paper, and can then use this option to
retrieve the plate itself.

The Print button listed at the bottom of the screen should be
used to retrieve a copy of the full-text article (or page) suitable
for printing. The format and resolution of the document created for
printing are controlled by each user's Default Settings, which can be
set via the
Article Service Preference Settings.
You should never use your browser's Print button to create a hardcopy of the page currently viewed
as it will produce poor
quality output. Please see the
Document Formats section
for more information.
